Assertion : Complexes of `MX_6` and `MX_5L` type (X and L are unidentate) do not show geometrical isomerism.
Reason : Geometrical isomerism is not shown by complexes of coordination number 6.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
C. If (A) is correct, but(R) is incorrect.
D. If both (A) and (R) are.incorrect.

Answer

C

Explanation

Complexes of the type `MX_6` and `MX_5L` do not show geometrical isomerism because change of position ofligands gives the same arrangement.
